Question 8061: And here's another problem that i don't know the steps to solve it out.
Find the equation of the perpendicular bisector of the line segment joining the points (1,2) and (3,1). Giving the answer in the form y=mx+c.
((i know it sounds easy, all i need is its formula or the steps to solve it. And that would really help me))

ok...the line required...you know nothing about it at all directly. You need to know its gradient and a point on the line. So.

1. find its gradient by finding the gradient of the line through the 2 given points. Once found, you know the gradient of the perpendicular line (don't you?).

2. find the point... it is the mid-point between the 2 given points, so figure that out.

3. find c from y=mx+c

4. you have your answer

jon.
